The invention aims primarily to provide a w and lerroveslde w fe -1 in a raising and lowering wheel drivenflgenerators of railway cars, although the same device is car equipment when applying or removing the same, for instance, the air tanks of the compressed air brake systems. 7

With the foregoing in view, the-invention resides in the novel subject matter hereinafter Fig. 3 is a horizontal section on line 3-3 of Fig. 1.

Fig. 4 is a horizontal sectional view on line l-4 of Fig. 1 showing more particularly a top plan view of the load-supporting cradle.

Figs. 5 and 6 are elevations of the cradle looking in the directions indicated by the arrows 5 and 6 of Fig. 4.

In the drawings above briefly described,

the preferred construction is illustrated, and A and arerive e or O herwi s cu ed et3 [to the side bars 16,1 Preferably, all eiids of the sha s 2 rel quare r herw s Shap 1 while this construction will be herein specifi-v cally explained, it is to be understood that within the scope of the invention as claimed, variations may be made.

A portable frame 10 is provided, mounted on front and rear axles 1112 respectively,

said axles being provided with appropriate I wheels 13. The front axle is of course swiveled, as at 14 andit is equipped with an appropriate tongue 15 by means of which the frame may be drawn from place to place, a

I-kto vertically side bars 16 of the frame 7 or .Feu 'blo ks 3.6

and steered.

The longitudinal and preferably other parts of said frame also,

are formed from angle metal bars, each havr, ,7 g V p threaded, each block having an inwardly deing a vertical flange 17 and a horizontal flange 18 projecting horizontally inward fromthe H V p e ta l bars-38, having upwardlydiverging lower edge of said vertical flange. Secured in the angles between the flanges 17-18 of the two bars '16, are four bearing blocks 19,.

36, while the flanges 40 are fastened by screws or the like 40 upon the inwardly declined ends 37 of said blocks. Preferably, these blocks are recessed as shown more particularly at 41 in Fig. 4, to snugly receive the flanges 39-40. The upwardly diverging arms of each bar 38 are connected by a horizontal bar 42 which is riveted or otherwise secured thereto, and two longitudinal bars 43 extend between and have their ends secured to the arm-connecting portions of said bars 38. Two longitudinal bars 44 also extend between and are secured to the blocks 36.

The construction just described, provides a simple and inexpensive, yet arigid, durable and very efficient cradle structure tov receive and retain a generator, compressed air tank or the like, when removing or applying it, and when carrying it from one place to anpther upon the truck. When a generator or other part is to be removed from a car, the truck is pulled or backed under said car and the crank or the like 34 is operated to raise the cradle snugly under the part to be removed. Then when this part is disconnected from the car, the cradle is lowered and the removed part is carried to the desired destination upon the truck. A reversal of these operations permits quick and easy installation of a generator, tank or the like upon a car.

As above stated, the details disclosed are preferably followed, but within the scope of the invention. as claimed, variations may be made.

I claim 1. In a device of the class described, four vertical screws and means for supporting and rotating them, four blocks through which said screws are threaded, said blocks having flat inwardly declined inner end portions, and two transversely disposed U- shaped bars having upwardly diverging arms secured upon said flat end portions of the opposed blocks, said declined block end portions being substantially one-half the length of said arms to effectively reinforce the latter against bending.

2. In a device of the class described, four vertical screws and means for supporting and driving them, four blocks through which said screws are threaded, said blocks having flat inwardly declined inner end portions, two U-shaped angle metal bars extending between the opposed blocks and having upwardly diverging arms, one flange of each arm being secured upon one of said fiat declined block ends while the other flange of each arm is secured against a fiat vertical side of a block, and longitudinal bars tying said blocks and U-shaped bars in fixed relation.

3. In a device of the class described, four vertical screws and means forsupporting and driving them, four blocks through which said screws are threaded, said blocks having rsonvov flat inwardly declined inner end portions, two U-shaped angle metal bars extending between the opposed blocks and having upwardly diverging arms, one flange of each arm being secured upon one of said flat declined block ends while the other flange of each arm is secured against a flat vertical side of a block, longitudinal bars connecting the arm-connecting portions of said U- shaped bars with each other, additional longitudinal bars secured at their ends to said blocks, and transverse bars above the arm connecting portions of said U-shaped bars and secured at their ends to the arms of these ars.

In testimony whereof I have hereunto af- {ixed'my signature.
